4.2 Hadoop2 Specific Inputs & Actions Use vendor, version and source input to configure the vendor, version and bundle source for the Hadoop2 version that needs to be deployed. Note: In many of the path related configuration parameters, the default value that appears contains $user. It should be noted that, it automatically gets updated to user name based on the value provided in user name input of node authentication. Other than this, there are few more Hadoop2 technology specific inputs as follows. Impetus Confidential Page 19 of 48

By default, it is enabled. When it is enabled, secondary Namenode column/input is disabled on node list. To deploy Hadoop2 cluster with SecondaryNameNode, user needs to disable high availability. Zookeeper component needs to be selected for high availability configuration. Currently during Hadoop2 cluster setup apart from Hadoop user also has provision to Impetus Confidential Page 21 of 48

setup nine more ecosystem components along with Hadoop. Those components are: 1. Flume 2. Hbase 3. Hive 4. Mahout 5. Oozie 6. Pig 7. Solr 8. Sqoop 9. Zookeeper Table 3: Hadoop2 Ecosystem Components Out of all these Hadoop2 components Hbase, Hive & Zookeeper take considerably more inputs than other components.

6 Chapter-5 Monitoring Hadoop2 Cluster A very important aspect of cluster management is monitoring its health, progress status etc. Ankush provides an exhaustive graphical representation and reporting system of varied aspects. There are numerous generic features / aspects that are covered across technologies as follows: Tiles: At very top various tiles are shown which can be classified into different categories like alerts, warning & information. Some of the tiles are clickable & opens up corresponding page related to it. In order to view Hadoop2 Technology specific tiles, refer to Tiles Summary section. Trend utilization of CPU, Memory, Network, Load and Packet Heat Map: This section provides CPU / Memory utilization HeatMap of cluster nodes. Each block corresponds to a node in the cluster. Color of individual block changes independently as per the value of utilization on the corresponding node. By default CPU utilization is shown. By clicking on required metric CPU or Memory its utilization heat map can be viewed. The node IP to which that HeatMap block corresponds can be identified by resting mouse pointer on it. Clicking on HeatMap of a particular node opens up node details page for that node. EcoSystem: This section provides details about various ecosystem components installed on cluster. Individual component details can be viewed by clicking on > against each component. This normally includes information related to Nodes, Configuration, Events, Logs and Audit Trails. However, the reporting system is further enhanced and provide lots of information about other components as well like Job Monitoring for a Hadoop2 cluster etc. Events: This summarizes various events occurred on the cluster. Logs: This functionality allows user to view or download logs of a cluster. Audit Trail: This functionality helps to track changes in the configuration. Please refer to Cluster Monitoring Section - Getting Started Guide for more information. Impetus Confidential Page 38 of 48
